Marginalia is a collection of notes from praying the Daily Office as set forth in the Book of Common Prayer (1979) of the Episcopal Church.

The Daily Office — Morning Prayer, Noonday Prayer, Evening Prayer, and Compline — is the ancient pattern of daily prayer that has shaped Christian worship for centuries. These entries are reflections, observations, and marginalia gathered along the way.

The name Marginalia refers to the notes one scribbles in the margins of a well-used book — not formal commentary, but the personal marks of an attentive reader.
